On December 15, 2025, Shanghai - According to the latest "2025 China Ethyl Hydrogen Silicone Oil Industry Deep Research Report" released by Oriental Wealth Network, the market size of ethyl silicone oil in China has reached 274 million yuan in 2024, and the global market size has exceeded 1.092 billion yuan. With the rapid development of high-end manufacturing, new energy, aerospace and other fields, the demand for ethyl silicone oil as a key basic material is growing at an average annual rate of 8%. It is expected that the global market size will reach 1.865 billion yuan by 2030.


Technological breakthroughs drive market expansion
Ethyl silicone oil is an ideal material for extreme environments due to its unique chemical structure (with Si-O-Si as the main chain and ethyl groups in the side chains), which provides properties such as ultra-low temperature resistance (maintaining fluidity below -70 ℃), high hydrophobicity, excellent electrical insulation, and chemical inertness. For example, Yunnan Nengtou Silicon Material Technology Development Co., Ltd. has upgraded its traditional vinyl silicone oil production line to a low ring vinyl silicone oil production line, with an annual production capacity of 5000 tons. The product purity has been increased to 99.9%, and the volatility has been reduced by 60%, directly meeting the demand for "ultra pure" materials in high-end electronic packaging, biomedical materials and other fields.


Diversified expansion of application scenarios
Industrial lubrication and sealing: Ethyl silicone oil, as a hydraulic system lubricant, can operate stably in a wide temperature range of -70 ℃ to 150 ℃, and is widely used in wind power equipment, high-speed rail bearings, and other scenarios. For example, the MY 2056 PES model ethyl silicone oil from Anhui Mingyi Silicon Industry Co., Ltd. has become a core component of aviation shock absorbers and automotive lubricants.
Cosmetics and personal care: its low surface tension makes it an ideal base material for face cream, lipstick and other products, which can not only form a breathable protective film, but also improve the gloss of the product. In 2024, the consumption of ethyl silicone oil in the cosmetics industry in China increased by 15% year-on-year, accounting for 22% of the global market share.
New energy and electronic packaging: In the fields of lithium battery separator coating, photovoltaic module sealant, etc., ethyl silicone oil can significantly improve the material's high temperature resistance and weather resistance through modification technology (such as introducing fluorine atoms), helping the new energy industry reduce costs and increase efficiency.
Competitive landscape and future trends
At present, the global market for ethyl silicone oil is dominated by companies such as Wacker Chemie from Germany, Dow Corning from the United States, and Blue Star New Materials from China. Chinese domestic enterprises are gradually narrowing the gap with international giants through technological iteration. The report points out that there will be two major trends in the industry in the future: first, environmental regulations will drive product upgrades, with low volatility and biodegradable ethyl silicone oil becoming a research and development focus; The second is the acceleration of vertical integration of the industrial chain, with top enterprises building a full industry chain advantage through mergers and acquisitions of upstream and downstream enterprises (such as silica mining and catalyst production).
